Show fish suggestions/questions for 150

So my blonde naso tang has outgrown my tank and after verifying that a LFS will take him, I just need to catch him and trade him in. Rookie mistake buying him but anyway. I am wondering what appropriately sized fish you might suggest for a replacement show fish? At the top of my list is either a longhorn cowfish or a powder blue tang. However, my concerns for the cowfish include that he will not be able to get enough food and might get picked on. Thoughts? My concern for the PBT is that he might pick on my existing fish (I ended up trading in a one spot foxface because he was a food hogging spaz that was freaking out the rest of the fish. All the fish in the tank were on edge all the time because of him and I am worried of a repeat issue.) Thoughts? Alternative suggestions? The only aggression I have in my tank right now is the Kole tang chasing the blenny every once in awhile so I am hoping to keep things fairly peaceful as I like seeing all of my fish all of the time.

My tank is a 150 with 40G refugium/sump with a Tunze skimmer that gets fed once a day.

The current tank inhabitants:
- Indigo Hamlet
- Marine Betta
- Kole Tang
- Longnose Hawkfish
- Swallowtail Hawkfish
- Lawnmower Blenny
- Green Mandarin
- Matted Filefish
- A Very large coral banded shrimp
- Asst corals, polyps, montiporas, frowspawn, caulastrea, clavularia, bubble coral
- Hermit crabs
- What snails the hermit crabs have not killed yet
 
Should have thought to add tank dimensions, I believe it is 72x18x28. The last two dimensions I am not 100% sure on but pretty sure that is close but the tank is definitely 6 ft long.

I forgot to add there is a large Crocea in the tank. Would one of the suggested triggers go after that?
 
I would go for the pbt as that is what you want and it should do fine your tank. Nice alternatives would include a powder brown or a purple tang. Make sure to quarantine them.
